IDA W. SCHMIDT, on NEW YORK, N. Y.

BATH-TUB.

SPECIFICATION forming are of Letters Patent at. 746,390, dated December 8, i903.

Application filed March 19, 1903. Serial No. 148,493. (No model.)

To all whom it may concern:

Be it known that I, IDA W, SCHMIDT, a citizen of the United States, residing in New York city, in the county and State of New York, have invented certain new and useful sons, its principal object being to so construct the tub that the person using it may enter and leave the same with the minimum exertion.

My invention will be found fully illustrated in the accompanying drawings, wherein- Figure 1 is atop plan view of my improved bath-tub. Fig. 2 is a longitudinal sectional view of the same. Fig. 3 is a transverse sectional view. Fig. 4: is a view of one end of the tub, and Fig. 5 illustrates a detail.

In order to carry out the object in view, the tub is provided with a water-tight door adapted to close an opening formed in one of the walls of the tub affording entrance to and exit from the tub. The water is admitted to the tub after the person has entered the same and properly closed the door, and in order to avoid the necessity of waiting for the water to acquire the desired level, which would be unduly protracted were it necessary to depend upon the usual pipes and other water connections, a temporary reservoir for holding the water, and between which and the tub there is a sufficiently capacious and valved communicating means, is provided.

The'general construction above outlined I find is perhaps preferably reduced to practice in that particular adaptation of my invention shown in the accompanying drawings.

In said drawings, a is an inner shell forming the tub proper, and b an outer shell.

These shells are preferably made integral and form between them a space 0, which constitutes the reservoir aforesaid, in which the water to be used is temporarily stored.

Entrance to the tub is afforded by an opening d, at which point the space between the shells a and b is of course closed, as at e, the material being, as shown, preferably shaped as a stepped jamb f, against which the correspondingly stepped faces 9 of the door 72. seat,

the door'bcing supported by hinges 1 and having suitable latches j for securing it closed. Between the door and its j amb may be placed a seal to make the connection water-tight.

l designates the fittings which are adapted to be connected to the supply, and m the fittings adapted to be connected to the waste 41, controlled by a valve 0.

In the bottom of the shell a is formed a relatively large opening 19, affording commu-- nication with space '0 and provided with a valve q, carried by a lever r, fulcrumed at s and having an operating device if.

u is a discharge-pipe affording direct communication between the interior of shell a and fitting m, into which latter it projects. In order to prevent the water in space ofrom flowing in by way of this pipe, a buoyant check valve 'U, only opening outwardly, is provided, said valve being carried by a valvestem w, guided. in spiders w L/ in the pipe.

I11 using the tub, the valves 0 and (1 being closed, water is first admitted to the reservoir 0 and its temperature taken by means of a thermometer 2, which may be projected down through an opening 1 in the top of shell or into the water. The person then enters the tub and closes and secures the door, whereupon the valve q is opened by means of its operating device t. This permits the water from the reservoir 0 to flow into the tub proper until a common level in boththe tub and the reservoir is reached, whereupon the valve q may be again closed.- Before leaving the tub the valve 0 is opened, permitting the water in the tub to leave the same by way of pipe to, while the water left in the reservoir may flow out by way of the fitting m direct. When the tub proper is free of water,the door may be opened,

so that the person may leave the tub.

It will be understood that the door h may be placed in any of the side walls of the tub.

Having thus fully described my invention, what I' claim as new, and desire to secure by Letters Patent, isi 1. The combination of a bath-tub having a closured entrance opening therein, a reservoir, a valved communicating means between the reservoir and the tub, and a valved disl 3.
